Chinese award-winning tutors’ perceptions and practices of classroom-based assessment

This study examines Chinese tertiary award-winning tutors’ perceptions and reported practices of classroom-based assessment. Seventeen tutors in the final stage of a national university teaching contest were individually interviewed. An interview framework was developed using three process dimensions of assessment for learning (AfL). A sequential and iterative analysis of resulting data was conducted based on Miles and Huberman’s protocols for qualitative analysis. Participants demonstrated a complex set of connections between perceptions and practices around issues of sharing standards, delivering feedback and response to external assessments. Results deviate from widely promoted principles of AfL and classroom-based assessment espoused in the international literature; in doing so, they challenge existing research and assumptions about the standardised and international nature of award-winning instructors’ assessment practices. Findings are discussed in relationship to understanding best practices in tertiary assessment, given emerging tertiary education markets. Practical implications for the further development of learning and assessment practices and theoretical implications for the AfL theory are also discussed.     

一种流媒体Caching策略

It is expected that by 2003 continuous media will account for more than 50% of the data available on origin servers, this will provoke a significant change in Internet workload. Due to the high bandwidth requirements and the long-lived nature of digital video, streaming server loads and network bandwidths are proven to be major limiting factors. Aiming at the characteristics of broadband network in residential areas, this paper proposes a popularity-based server-proxy caching strategy for streaming media. According to a streaming media popularity on streaming server and proxy, this strategy caches the content of the streaming media partially or completely. The paper also proposes two formulas that calculate the popularity coefficient of a streaming media on server and proxy, and caching replacement policy. As expected, this strategy decreases the server load, reduces the traffic from streaming server to proxy, and improves client start-up latency.     

屯堡聚落的典型特征空间探讨

通过调查分析,发现典型屯堡普遍具有一定的空间特征,这一空间特征与其形成的历史过程相关,并得以延续至今.其中,寨墙寨门、主次街巷体系和中轴主街以及村口塘是其中较为典型的三项.即寨墙和寨门可以确定出较为规整的聚落边界;主街作为全村的主要中轴线与各条次巷相连,形成尺度差异明确的主次巷道体系,各种重要建筑如村庙和戏台沿主街布置,并紧邻场坝;村口塘则位于村庄中轴线延伸的寨门前,与中心场坝遥相呼应;这几种空间模式所反映出的结构严整、主次分明、层层围护的军事卫所空间组织特征,与历史文献中记载一致,承载了屯堡历史上抵御外敌的重要村落历史记忆;在"屯戍体制"逐渐瓦解后仍能在后代的村落演变中得以保存,仍然是全村各种重要的仪式活动的中心发生地,同时在"屯堡"主体性的延续与重构中扮演重要角色,成为了屯堡村落中鲜明的文化场域.     

中学生物学教学应贯穿正确的思想观点

在中学生物学教学中经常能够听到类似“鸟为了飞翔而长有翅膀”的说法,“鸟”真的能够“为了飞翔而长有翅膀”吗?答案是否定的。在教学中,这是一种思想性错误,那么,为什么会出现思想性错误?1生物学教学中的思想性错误及其根本原因教学的思想性是指在教学中要用正确的观点阐述教     

在生态旅游中渗透生态环境教育

全球化背景下生态危机重重,然而人们的生态意识浅薄,生态环境教育迫在眉睫;我国生态环境教育面临社会现实的严峻挑战;生态旅游是具有保护自然生态与文化多样性,及维护当地人们生活双重责任的旅游活动,具有较强的生态环境教育功能,在生态旅游中渗透生态环境教育行之有效.     

城市化进程中的农民工社会保障

农村发展中所释放出来的过剩人口不断向城市转移,是城市化进程中的必然现象,随之而来农民工社会保障问题日益凸现。本文将其置于城市化进程中,从客观实际和有利于城市化进程的角度出发,提出要建立面向农民工的社会保障制度,并在分析其特殊性和可行性基础上来探讨应该如何去建构面向农民工的社会保障制度。

Heat transfer characteristics of air cross-flow for in-line arrangement of spirally corrugated tube and smooth tube bundles

An experimental study on heat transfer and resistance coefficients of linearly arranged smooth and spirally corrugated tube bundles in cross-flow was performed. The heat transfer and resistance coefficients are presented in this paper with transverse and longitudinal tube-pitch and tube geometries taken into account. The experiment's results can provide technical guidelines for application to horizontal air preheater with arranged in-line spirally corrugated tube bundles, especially to the air preheater for CFBCBs (Circulating Fluidized Bed Combustion Boilers).
